Detailed explanation-1: -Nitrification. Nitrification is the process that converts ammonia to nitrite and then to nitrate and is another important step in the global nitrogen cycle. Most nitrification occurs aerobically and is carried out exclusively by prokaryotes.

Detailed explanation-2: -Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate.

Detailed explanation-3: -Nitrification. Nitrifying bacteria in the soil convert ammonia into nitrite (NO2-) and then into nitrate (NO3-). This process is called nitrification. Compounds such as nitrate, nitrite, ammonia and ammonium can be taken up from soils by plants and then used in the formation of plant and animal proteins.

Detailed explanation-4: -Denitrification. Denitrification is the process in which heterotrophic and autotrophic bacteria convert nitrates into nitrites and then to nitrogen gas.
